Arm/Forearm weight +very fast chromatic octaves

Less tension in your hand is what it comes down to.[/quote]

Very good point. Less tension. and does not mean NO TENSION.---

 

hello everybody thanks for all your replies.

i appreciate

but still i have a problem about many fast chromatic octaves....

 

here you go, playing 4,5,4,5,4,5,fingers....for a while and perhaps for few years and treated as a dessert for every practice session-including other major works.

and good luck, by all mean dnt injur your fingers..

 

I disagree - I don't play chromatic octave runs with strict alternating fingers 4 and 5. Because it is not ergonomic to use the 5th finger on a black key and the 4th finger on a white key what would happen this way. Instead, as others wrote already, use the finger 4 for black keys and finger 5 for white keys. Or better, if you have large hands, use also finger 3. E.g., right hand starting from c to the next higher octave: c: 5, c#:4, then 5,3,4,5,4,5,4,5,3,4,5 (next c). This way a lovely legato is possible (unfortunately not for the other notes played with the thumb), and with time it can get very fast too without creating unnecessary tension in the wrist.

 

sorry Olaf, that was my oversight...4ths on black key only, 5 on white keys eg b and c;e and f.
